Динамик ВЧ SCANSPEAK D3004/604000. Инструкция на английском языке

TWEETER                                                 D3004/604000
This 1” compact Illuminator beryllium tweeter is an example of a big sound in a small
body. As beryllium is a material characterised by great stiffness, light weight and
high damping, the beryllium diaphragm offers all the properties required to
reproduce excellent sound. And indeed, the 1” tweeter sounds great. It has a very
low distortion and a distinct clarity that brings out the best in all types of music.
KEY FEATURES:
· 1" Beryllium Diaphragm (99% pure Be)    · Large Roll Surround f. wide dispersion
· Patented Symmetrical Drive (SD-2) motor  · Compact Non Resonant Alu Rear Champer
· Die Cast Housing & Face Plate           · Sound Transparant Protective Grill
